The GB administrators have asked us to report the cash price, where it is lower than the credit price. If you'll note my reporting of the Valero and 76 on N Mathilda in Sunnyvale, I report the credit price in the comment as an offset to the cash price I report. Also, see my reporting of World nearby. There my comment is Cash=Credit. The reason I mention it is that they have a fairly low price.

The Valero at 4625 San Juan Ave & Winding Way, Fair Oaks does not have diesel according to the Valero web site and the Master Station List. If you are sure you saw diesel at this station please update the MSL.
Need help? Contact me.
I will remove the price you posted so those looking for diesel will not be fooled into going to this station.
